Theory of Knowledge


Theory of Knowledge, colloquially referred to as TOK, is a compulsory course for all students earning the IB diploma. In the course, the aim is to help IB students become effective critical thinkers, with a greater goal being to develop IB learners: 'internationally minded people who, recognizing their common humanity and shared guardianship of the planet, help to create a better and more peaceful world.' The Theory of Knowledge course, along with the Extended Essay, are intended to unify the other academic subject of each student.
The course is centered around the study of 'Ways of Knowing', 'Areas of Knowledge' and 'Knowledge Issues', and encourages students to question what they already know in an abstract manner, by asking questions such as 'What counts as knowledge?' or 'What is the value of knowledge?'
The classroom environment is usually very discussion-based, and the course thus has a secondary function of helping students develop their oral expression skills.  ( more at
